BEVELING-MACI-IINE.

Specification of Letters Patent.

Patented Sept. '7, 1909.

Application filed January 21, 1905. Serial No. 242,190.

To all whom 'it may concern:

Be it known that I, VERNON BOYLE, a citizen of the United States, andresident of Paterson, in the county of Passaic and State of New Jersey,have invented a new and useful Beveling-Machine, of which the followingis a specification. V I

My invention relates to beveling machines, with the object in view ofproviding means for presentin the plate to be beveled to the cutter atdi 'erent, distances therefrom as may be desired without tilting thecarriage on its track and to provide means within convenient reach ofthe operator for throwing a feeding mechanism into and out of operation.r V

In the accompanying drawings, Figure 1 is a View of. the machine in sideelevation, Fig. 2 is a top plan view, Fig. 3 is an end view, Fig. 4 isan enlarged transverse section in the plane of the line AA of Fig. 2,Fig. 5 is a view of the: worm wheel in side elevation, Fig. 6 is anenlarged view in detail showing a portion of the track in elevation withthe tension or take-up device in position, Fig. 7 is an end view of thesame, Fig. 8 isa section through the pivoted connection of the trackwith the support,

Fig. 9 is a partial view of the back of the track at the point where theadjustment takes place, a portion of the support and adjusting devicebeing shown in position, and Fig. 10 is a transverse section through thesame.

The pedestal is denoted by 1 and this is surmounted by a bed piece 2provided with' oppositely extending flanges 3 and 4 at one side thereof.The cutter supporting frame 5 is mounted and is made adjustablelaterally by means of a screw feed 6 of well known or approved form. Inthe frame 5 the cutter spmdle 7 is mounted and carries a head 8 to whichthe beveling cutter may be secured. The cutter head and its operatingspindle are adjusted laterally bodily together with the frame 5.

The plate supporting table is denoted by 9. This table is provided witha depending flange 10 on the face of which, toward the bed piece 2,there is a dove-tailed recess 11 for the reception of a dove-tailedtrack 12;

The track 12 is pivoted to the flange 3 of the bed piece 2.This'pivotalconnection of the track is made by providing the flange 3with a round hole 13 in which is seated a pivot piece 14, the said pivotpiece being provided at its outer, end with a flange 15 which laps overthe edge of the hole 13 in the flange 3 and at its inner end is providedwith a boss 16 which projects into a socket 17 formed in the track, thepivot piece 14 being secured to the track 12 by means of screw bolts 18,passing through the pivot piece into the track. This structure is shownindetail in Fig. 8. The track 12 and the parts supported thereon areadjusted vertically by means of a hand screw 19 seated in a boss 20 onthe upper edge of the track 7 and overlapping the flange 4 of the bedpiece 2, the said, screw resting with its lower end on the top of theflange 4.

The parts are held in the desired adjustment by means of a tail nut 21working on the threaded end of a bolt 22 seated in the track 12 andextending through a vertically elongated slot 23 in the flange 4. Thisstructure admits'of tilting the track and the table 9 which is, ineffect, a carriage for moving the plate into engagement with the cutter,towardand away from the cutter to cause the latter to cut deeper orshallower as may be desired, and also for accommodating the plates ofdifferent thicknesses, while the adjustment of the cutter bodily towardand away from the table 9 provides for locating the cut at or such adistance away from the edge of the plate as may be desired.

'The. clamp for holding the plate on the table .9 is denoted by 24 andmay be of any well known or approved form. The table line is providedwith bars 25, and 26, extending laterally therefrom to any distance thatmay be desired for supporting plates of dif-.

ferent widths. One of these bars, in the present instance the bar 25also serves as a support for-a hanger 27 which has at its lower endabearing 28 for the support of the forward end of the feed operatingshaft 29. Thefeed operating shaft 29 is provided on its rearward endwith a worm 30 and on its forward end with a hand wheel 31. The worm 30engages a worm wheel 32 which may be locked to and released from a drivewheel 33 as follows :The drive wheel 33 is loosely mounted on theelongated hub 34 of the worm Wheel 32, the latter being mounted on anaxle 35 depending from the table 9. On

the extended hub 36 of the drive Wheel 33 the hub 37 of the clutchisloosely mounted.

The clutch 37 is provided with a plurality of arms radiating from itshub in the present instance three arms equidistant apart. These armsaresimilar and similarly equipped, one

of them, denoted by 38 being shown in section in Fig. 4, and providedwith a pin 39 set therein and extending loosely through a boss 40 on thedrive wheel 33, and of such length that when the clutch is thrown intoposition to lock the worm wheel to the drive wheel, as shown in Fig. 4,the pin 39-will enter one of a series of perforations 41 in .the sideface of the worm wheel 32 but when 7 the clutch is thrown in theopposite direction it 'will'withdraw the pin 39 from engagement with theworm wheel 32 leaving the wheel 33 free to revolve without affecting theworm wheel. It is understood that the pins on the other arms are similarto the pins 39 and pass through similar bosses on the drive wheel 33.

v forwardlyito Within convenient reach of the operator and thereprovided with a handle 49 which may be grasped by the fingers of theoperators hand when the hand of the operator rests on a support 50 fixedto and projecting forwardly from the end of the table 9. By grasping thehandle 49 while the operators hand rests on the support 50, the lever 47twill be rocked in a direction to throwthe clutch in a direction torelease the pins 39 from the worm wheel and, as long as this grasp iscontinued, the table or carriage with the plate thereon may be advancedand returned along the track 12 at pleasure. As

soon as the grasp is released from the lever 49, the spring 51 on therod will lift the sleeve 44 and carry the clutch upwardly into positionto throw the pins 39 into lockin engagement with the worm wheel 32 andthen, by turning the hand wheel 31, the operator may operate the wormwheel and together with it the drive wheel 33, and hence move thecarriage and plate to the cutter because of the connection of the drivewheel ,1 with the track as follows 2 A band 52, in the present instancea wire, is made fast at one end to a pin 53 on the track 12 and extendsthence along the face of the track 12 to the periphery of the drivewheel 33 around 7 which it passes and thence onto the dependmg arm 54 towhich it is attached as at the point 55. .The arm 54 is pivoted at itsupper end at 56 to the forward end of'the track and at its lower end thesaid arm is connected by a link 57 with an. upwardly extending vibratingarm .58 pivoted at 59 .to the track 12 and connected at its upper end bya spring 60 with a pin 61 on the face of the track 12.

The-spring 60 exerts its tension in a direction to draw the arm 58toward the pin 61 and hence to force the arm 54 through the linkconnection 57 away from the track 12 and thus exerts a pull on the band52 sailicient to' take up any slack that may tend to form when themovement of the table or carriage 9 is reversed; It also provides as atake-up or tension mechanism to provide for any contraction or expansionof the wire band 52 under different degrees of temperature.

hen the worm wheel 32 is locked to the wheel the turning of the handwheel 31 in the one direction or the other will advance or return thecarriage or table 9 and plate thereon but when the clutch is thrown outof locking position, the carriage may be freely moved by hand, the wheel33 rotating idly by its engagement with the band as the carriage ismanipulated by the direct push or pull of the operator.

The structure has the advantage of being simple and providing formanipulation of the plate carrying table or carriage either by thedirect thrust or pull of the operator or by the intervention of the gearfor multiplying power at the expenseof time while the plate carryingtable or carriage itself is moved along the track to which it may befitted with great accuracy and this engagement of the carriage with thetrack is not disturbed when the track is tilted to bring the surface ofthe table nearer to or farther away from the cutter. The cutter may alsobe mounted in a heavy frame which will prevent it from hurtful orannoying vibration and this frame itself being bodi y movable along thebed frame will provide for the lateral adjustment of the cutter withoutchanging the relation of the cutter spindle to its supporting frame.

hat I claim is 1. The combination with a suitable support, a trackpivoted to said support and arranged to tilt edgewise in a verticalplane, means for tilting the track and holding it in tilted adjustmentand a plate supporting carriage mounted to slide along the side face ofthe track, of a cutter in position to engage the plate as the carriagemoves past it.

2. The combination with a plate supporting carriage provided with ahandle and a pivoted track along which it is arranged to slide, ofgearing for forcing the carriage along the track, means under thecontrol of the hand of the operator while grasping the said handle forthrowing the gearing out of operation topermit the carriage to be sliddirectly under the thrust and pull of the operator and a cutter inposition to engage the plate carried by the carriage.

3. The combination with a plate supporting carriage provided with ahandle and a track along which it is arranged to slide, of

a drive wheel carried by the carriage, a band attached to the track andengaged with the said drive wheel a worm wheel carried by the carriage,a worm under the control of the operator for driving the worm Wheel anda clutch under the control of the hand of the operator while graspingthe said handle for locking the worm wheel to and releasing it from thedrive wheel and a cutter for engaging the plate carried by the carriage.

4. The combination with a plate supporting carriage rovided with ahandle and a track along ich it reciprocates, of a band attached to thetrack, a drive wheel carried by the carriage and engaged with the band,a Worm wheel carried by the carriage, a worm under the control of theoperator for operating the worm wheel, a multiple armed clutch providedwith locking pins for locking the worm wheel to and releasing it fromthe drive wheel, a lever under the control of the hand of the operatorwhile grasping the said handle for releasing'the clutch, a spring forthrowing the clutch into locking position and a cutter for engaging theplate on the carriage. y

5. The combination with a plate supporting carriage, a pivoted trackalong which the carriage slides, a band secured to the track, ataking-up mechanism consisting of a system of spring actuated leversinterposed between one end of the band and the track, a drive wheelcarried by the carriage and engaged with the band, means under thecontrol of the operator for actuating the drive Wheel and a cutter inposition to engage the plate on the carriage.

6. The combination with a plate supporting carriage, a track on which itslides and a track support, of a pivot piece extending through the tracksupport into engagement with the track, means for locking the pivotpiece to the track, means for locking the track in different tiltedadjustments on its pivotal support and a cutter in position to engagethe plate carried by the carriage.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 13th day of January 1905.
